Vegas is just the first leg of Marvin’s last holiday as a single man though as after they’ve partied their way through the hotels and clubs, they’ll be moving on to Miami.They might have the money to rock up in designer clothing but all four of the boys stuck to true stag do tradition and wore matching navy t-shirts emblazoned with the words ‘DYDTOUIR’ written on the front and ‘Vegas Miami 05 2012’ on the back.

As they made their way to the waiting limo bus to take them to their hotel, it’s clear they were getting ready to party as JB tweeted: ‘Uh oh…vegas!!J x.’

The boys have previously spoken of their plans for Marvin’s ‘epic’ stag do, admitting they wanted to keep it all under wraps to surprise the groom-to-be.

Aston said in a recent interview: ‘You heard of the Hangover and Hangover 2? What we are planning will be Hangover 3.

‘His plane ticket won’t have the destination written on it and the pilot won’t announce where we’re flying to. It’s all very secretive.’

JB also hinted at what might be in store for 27-year-old Marvin, adding: ‘It’s going to be mental. We’ve hired an ex-MI5 agent to plan the stag party. It’s going to be a secret military operation because we want it to be kept secret from both Marvin and Rochelle. She’s not happy about it.’

And Oritsé had his own ideas of how it would go down as well, saying: ‘After the guys got me a stripper for my birthday, Marvin better be afraid! We can tell you it’s going to be a stag do of “Hangover”-style proportions. We’re talking dropping him off in the middle of the desert, tattoos, the works.’
